Hi I am Ashraful Alam writing China,I have come in China by CSC scholarship. I have got 4 years student visa here. I have also taken my wife and doughter in china 7 months ago.When they came china, they did not attest marriage certificate and birth certificate from china embassy in bangladesh. one time china Govt. extend my family visa for 6 months. But they said me if i do not attest that certificate from china embassy in Bangladesh, they will not extend my family visa. If I or my family will not go Bangladesh for attestation, it will possible to take attestation from embassy by my relatives. I will send my documents (my visa photocoy,my wife's and daughter's visa copy).
